Hi again
so to answer the questions - running in cached or online or OWA does not make a difference the results are consistently incorrect
We are running Exchange 2019 so cannot see a simple way to reindex the database as it is not the same as Exchange 2016 so does not have an index file location.
The issue affects everyone outlook 2016 & 2019 users so I was suspecting Exchange as the issue only appears to have started since we installed cumulative update 7. I have since installed cumulative update 8 but this has made no difference.

The only way I have found to make it return the missing results is with Outlook 2019 is to change the search string to include this year so if I were searching for content then I would use "content received:this year"
Which seems to bring in the missing results
Any ideas anyone???
